Hopefully someone here will spend the time to help me. I have spent time googling my problem and i am not certain on what the right thing to do is.I shut my hps off so i could take the sick plants out of the growroom and take some good quality pics . These pics should be of excellent quality as to show my problem to you guys with ease. The story goes like this......

I have 6 green crack strain grown from clones. I have them in ff soil happy frog I consistently check and adjust my filtered water to keep my ph at 6.5 to 7.0. I vegged for 20 days at 24/0 mh600watt everything went good on humboldt nutrients grow natural and moderate super thrive. my temps have been a slight problem and sometimes at night drop to 60 degrees . It is almost always between 70-80. I water every 3 days . they are draining well.

Now im in my 3rd weeki of flower and im noticing that the stems are getting very purple and the top leaves on two of my girls are getting yellow. Even the buds on one of the girls are getting a purple color. Some of the leaves look like the claw effect . I turned the heater so its not blowing on my leaves . here is some pics of the worst one . They all seem to be makling some really nice buds that smell and look great . dont want to lose it now. here is the pics let me know what you thgink it might be .....thanks in advance

Why do they get the red stems?

my plants were doing this when i had root aphids. I blamed the early yellowing and red stems on alot of other things before I finally figured it out.

I have been worried about the roots also .So I took a peak and transplanted one into a slightly bigger pot. This gave me the chance to take a quick look at the roots and they looked bright white and not moldy or anything like that .

The second picture looked like Nitrogen deficiency but that usually starts with the older leafs and works its way to newer leafs. Plants usually starve themselves of Nitrogen when put into flower so what week are you on? It looks like your around week 5-6 which I see many people get N def around this time.
I could be wrong about the N def so take a look at the deficiency posters on google.

View attachment 1993728 Well buddy im not sure but im thinkin that it has to be a sulfer, or iron. Not sure though What are your nutes schedules?

 

[mouse]

I would say your a little short on N but its too late in flower to be boosting them now. Yellowing of leaves during flower normally starts at the bottom. You have yellowing at the top. What have you fed them over the past month or so ? Do you ever ph up and then down or down and then up your water ?

What kind of water filter do you use ? I find straight tap water (sometimes as high as .4 EC) does me nicely and I never PH when I am giving my plants water. The point is to water them.

You could be experiencing a lockout due to too much of another nutrient. I am unsure and until I have details on your feeds I am unable to progress your issue further

New growth turning yellow is a sulfer def. You need some epsom salt. Real easy fix. Dont wait so long next time.

Some strains turn purp. It is a desirable trait.
I would not worry about it, I have seen red stems during veg and flower. Correct the sulfer def and your plants will be fine

Buy a good book like Mel Franks growers guide and be careful listening to advice from potheads on pot forums.

Im using humboldt bloom natural at about 5-10 ml a week also im using a spoonfull of mallases a week since flowering. I am on week 3 flowering at 12/12 . As far as water goes I purchase water at the crystal geyser machine which I have found to be cleaner than any bottlede water. I have been able to keep my ph between 6.5 and 7.0 with stability from the fox farm happyu frog soil. I have my grow area well ventilatedwith a 500cfm fan and a small 1/4hp dayton fan . I live in southern california and when the sun is nice I will take my girls out of the room for some sun. I can really see that they are tyrying to communicate with me the defficiancy but Its difficult to tell what they need. I think the epson salt might be good . but I dont know

Thanks Bone! I just read your link . which ive read before and noticed a description that points to sulfur . I will try the epson salt tomarrow am and see . I dont think it can hurt to try that .

do you know your soil ph ?? vey underestimated subject and how close to the light they look a lil crispy and humidity ?

 

[mouse]

I dont know the concentration on your foods but that sounds strong for such a young plant. Also I keep my plants on grow food for the first week or two of flower to prevent nitrogen def and ensure that I can really cut down the N towards the end of flower.

Take all of our advice, formulate your own opinion of whats wrong.

Personally I have never seen a sulfur def on a plant in decent soil with high quality nutes.

Just my 2 cents

 

[0calli]

cud be a lockout for the sulfur

mixed up some ph,d water (3 gallons at 6.5) and added 2 tsp of Epsom salt . I distributed it evenly to all 6 plants . Also I mixed in about a1/4 tsp in a 1/2 gallon for a foliar spray . I put that in carbonated Perrier water . I sprayed the leaves with a fine mist twice yesterday. Today when lights came on I looked and it obvious that the purple is already going away . I am in about week 4 flower . They all look pretty happy so I think the epson is working . I'm going to feed them with just clean ph,d water next time in 2 days and if they continue to improve on losing the redness I'll do epson next week

is that light bleaching? how close is that one to the light? not ideal to have any yellowing during flowering, you will reduce the harvest.
